  Variation in the oil yield and composition of essential oils from fifteen differently Eucalyptus crebra (E. crebra) trees adopted of Faisalabad was presented. Hydro-distilled leaves of Eucalyptus crebra ranged 0.29-1.33 % of essential oil. Extracted oils were resolved and identified by GC/FID (Gas chromatography) on Carbowex-20 M packed glass column. Maximum components (33) were detected in the oil of two different trees (i.e. tree No. 6 and 10). A total of 33 components were detected, out of which 6 amounting to approximately 60% of the oil were identified. In Eucalyptus crebra oils six components (α-pinene, β-pinene, Δ3 carene, α-phallendrine, Limonene and 1, 8-cineole), were positively identified. The principal constituent 1, 8-cineole, found in the fifteen oils of different trees, was ranged (11.87-43.80%). The other major components were ranged: β-pinene (0.20-12.13%), α-pinene (1.68-18.23%), Δ3 carene (1.32-5.63%) and α-phallendrine (0.55-7.98%). Only in the oil of one tree limonene (2.37%) was found. Chemical composition of oils from tree to tree varied significantly which may be due to the differences in their genetic make up (e.g., age, height) and may also be the effect of salinity. Eucalyptus crebra trees oil shown 1, 8-cinole percentage more than 70%, for that reason oils of Eucalyptus crebra trees under study were found suitable for medicinal purposes.

  Urinary excretion of Salicyluric acid (SUA) was investigated in twelve healthy male volunteers. Urine sample was collected up to 10 h. The concentration of salicyluric acid (SUA) a major metabolite of aspirin was measured colorimetrically. The concentration of salicyluric acid (SUA) (mean±SE) in urine was 200.5±14.9 μg mL-1. Excretion of salicyluric acid was extremely variable and depends upon pH of urine. The results show that the mean±SE values for pH of the urine was 6.24±0.11, amount of drug excreted as salicyluric acid was 63.5±12 mg and percentage of dose excreted was 10.66±1.98. The cumulative amount of dose excreted as salicyluric acid was 191.3±58.2 mg and cumulative percent of dose excreted as salicyluric acid was 62.45±1.06. There is statistically slight variation in urinary excretion of SUA data when compared with foreign investigated values.
